For the ultra sparc, SunC 4.0 cc -fast -Xa -xO5, running 'des_opts'
gives a speed of 475,000 des/s while 'speed' gives 417,000 des/s.

+I believe the difference is tied up in optimisation that the compiler
is able to perform when the code is 'inlined'. For 'speed', the DES
routines are being linked from a library. I'll record the higher
speed since if performance is everything, you can always inline
